DOOR-BINDER.

SPECIFICATION forming part of Letters Patent No. 630,811, dated August8, 1899.

Applicatioh filed January 25, 1898. Renewed February 18,1899. Serial No.706,066. (No modeLl To all whom, it may concern Be it known that I,OLIVER H. KINGSLAND, a citizen of the United States, residing at NewYork, (Brooklyn,) in the county of Kings and State of New York, haveinvented a certain new and useful Improvement in Door-Binders, of whichthe following is a specification, reference being had to the drawingsaecom panying and forming a part of the same.

The present invention relates to improvements in door-bindersthat is, indevices for holding a door, especially a fire-door, tightly against thewalls of the door-space or other passage through the wallsand theinvention relates particularly to that form or arrangement ofdoor-binders, known as duplicate or multiple binders, used for thepurpose of holding doors, one arranged to close a doorspace on theinside of the building-Wall and onelto close the space from the outsideof the wal The invention consists of a door-binder of the kindindicated, the buffer, binder, or door engaging and holding part ofwhich is adjustably mounted or carried on the part of the binder whichis secured to the walls of the door-space.

Referring to the drawings, Figure 1 indicates a plan view (a Viewlooking down on the upper edgeof the doors) of one form of doorbindermechanism embodying my invention, the walls of the door-space beingshown in horizontal section and one door being shown closed, while theother is in open position. Fig. 2 is an elevation view of a binder forholding the lower edge of the door. Fig. 3 is a vertical section of thesame on the plane a a. Fig. 4 is a plan View of the same with theadjustable binding part removed. Fig. '5 is a modification to be morefully explained in the following description.

Referring to the drawings in detail, A represents a doorway-space, and BB side or vertical walls inclosing the same.

0 represents an outer door, and D an inner door, the latter being shownin closed position, while the former is in open position. These doorsmay be hung and operated by any proper means, though ordinarily theywould be hung on trolley-tracks and so arranged or provided withoperating mechan ism that they will automatically close, as in the caseof a high or unsafe temperature in the neighborhood of thedoorway-space, various means for causing such doors to remain open andto automatically close in event of fire occurring near the doorway-spacebeing well known.

E represents one of the binders, which preferably is in the form of thefrustum-bracket shown, carrying the frictionroll or wheel F, and ismounted on the toothed or notched base-plate G, which base-plate isadjustable on the foot H of the side bar I, attached to and arranged atright angles to the slide-bar J, said foot H being also provided withteeth K and notches L that mesh with the notches and teeth of the baseof the binder, the binder being held in fixed position on the foot by ascrew M and its base being guided, when moved for adjustment, by theupwardly-projecting rib N.

When this device is applied to the walls of, say, a fire-door space, theslide-bar J of one such binder mechanism is fixed to the inner ordoor-space face of one of the walls, while the side bar bears againstthe.outer face of the wall, as seen in Fig. 1, and another bindermechanism of similar form is fixed to the other side of the wall, thetwo slide-bars lying one upon the other, screw-bolts 0 being used tohold the bars in place on the wall, which bolts pass through holes P andQ in the slide-bars, one or both of which holes may be elongated, asshown in Fig. 2, for the purpose of adjusting the bars to differentthicknesses of doorspace walls.

In case of applying this mechanism, as shown in Fig. 1, it is supposedthat the binder engages the lower edge of the door, the thickness of thebase of the binder and the foot of the side bar being together about thethick ness of the ordinary door-sill. Assuming that the binder isadjusted so that the space between the periphery of its wheel and theface of the side bar properly conforms to the thickness of the door, itwill readily be seen that in case of a door closing its closing verticaland bottom edges will be guided by and brought to close contact with theside walls of the door-space by the binder and its wheel, thus insuringthat the door he held tightly to the walls and prevented from springingor warping, so as to open the door-space. I apply this means ofadjusting the binder on its support to binders of other forms-such, forinstance, as to a binder used to hold the vertical edge of a doorbetween its top and bottom. Thus in Fig. 5 I show slide-bars R and S ofconstruction substantially as already described, but which carry sidebars T, running horizontally instead of vertically, as in the case ofFig. 2, and these side bars are provided with teeth and notches U, whichengage corresponding teeth and notches in the base V of the binder W,which binder is adapted in form and attachment to the door-space wallsto serve as a butter to stop the door as well as to bind its edge to thewall. Byloosening the securing-bolt X this binder may be adjustedhorizontally, so as to determine the extent that the edge of the doorshall lap the walls. By these means I provide an adjustable support fora door-binder, whereby the binder can be readily adjusted on itssupporting parts to the thickness of the door or to the extent of it'swall-lap, as also the binder carrying parts of a duplicate arrangementof binder mechanisms may be made adjustable to suit differentthicknesses of wall, so that one form or size of binder mechanism can beutilized for various thicknesses of door-walls and various thicknessesof doors.

\Vhat is claimed as new is 1. A door-binder consisting essentially of abar J adapted to be secured to the passagei'ace of a door-space wall,the side bar I secured atright angles thereto and adapted to bear uponone of the side faces of the wall and notched and toothed, and a binderdevice also notched and toothed and adjustably secured to said sidebars, for the purpose set forth.

2. In combination with aslide-bar J having the side bar I and foot H,the binderEadjustably secured to said foot by notched and toothedconnections and provided with the friction-wheel F, substantially as andfor the purpose set forth.

3. In combination with the slide-bar J carrying a side bar I and foot H,the binder having anotched and toothed connection with said foot, and arib N for guiding the binder when being adjusted, and means for fixedlysecuring said binder and foot together.
